This study aimed to develop and investigate the psychometric properties of the Perceived Telemedicine Importance, Disadvantages, and Barriers (PTIDB) questionnaire for healthcare professionals (HCPs) in Egypt. This study was conducted in three phases: (1) development of the questionnaire, (2) preliminary testing of the questionnaire, and (3) investigation of its validity and reliability using a large survey.
A cross-sectional survey was conducted over two months. A convenience sample of 691 HCPs and clerks from 22 governorates accessed the online survey. The construct validity was assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and internal reliability.
The initial Eigenvalues showed that all 19 items of the questionnaire explained 56.0% of the variance in three factors. For Factor 1 (importance), eight items were loaded on one factor, with factor loading ranging from 0.61 to 0.78. For Factor 2 (disadvantages), seven items were loaded on one factor with factor loading ranging from 0.60 to 0.79. For Factor 3 (barriers), four items were loaded on one factor, with factor loading ranging from 0.60 to 0.86. The CFA showed that All loadings ranged from 0.4 to 1.0, with CFI = 0.93 and RMSEA = 0.061. All the factors had satisfactory reliability; 0.87 for ''Importance'', 0.82 for ''Disadvantages'', and 0.79 for ''Barriers''.
The PTIDB questionnaire has an acceptable level of validity and internal consistency, at a readability level of 12th grade. The retest reliability, however, still needs to be tested.
本研究旨在开发并检验针对埃及医疗保健专业人员（HCP）的感知远程医疗重要性、劣势和障碍（PTIDB）问卷的心理测量学特性。该研究分三个阶段进行：（1）问卷开发，（2）问卷初步测试，（3）使用大型调查研究其有效性和可靠性。
横断面调查在两个月内进行。从 22 个省中，方便抽取了 691 名 HCP 和职员参加在线调查。使用探索性因子分析（EFA）、验证性因子分析（CFA）和内部可靠性评估结构效度。
初始特征值表明，问卷的 19 个项目在三个因素中解释了 56.0%的方差。对于因素 1（重要性），有 8 个项目被加载到一个因素上，因子负荷范围为 0.61 至 0.78。对于因素 2（劣势），有 7 个项目被加载到一个因素上，因子负荷范围为 0.60 至 0.79。对于因素 3（障碍），有 4 个项目被加载到一个因素上，因子负荷范围为 0.60 至 0.86。CFA 显示，所有负荷范围从 0.4 到 1.0，拟合优度指数（CFI）为 0.93，RMSEA 为 0.061。所有因素的可靠性均令人满意；“重要性”为 0.87，“劣势”为 0.82，“障碍”为 0.79。
PTIDB 问卷具有可接受的有效性和内部一致性水平，可读性水平为 12 年级。然而，重测信度仍需进一步检验。
